1620b (see below).
Referring now to Figure 2, being such as used for from what network node 200 executed to wireless device it illustrates according to the embodiment
The method of 300a granting resources.
S102: network node 200 is obtained for the instruction to wireless device 300a granting resources.
S106: network node 200 sends the license for the resource in sTTI frequency band to wireless device 300a.The license
Including index, and the index identifies position of the resource in sTTI frequency band.
The license sent in step s 106 can be considered as quickly permitting.
At least two can be provided in (single) orthogonal frequency division multiplexing (OFDM) symbol in sTTI frequency band in this way
License, and therefore send the license as at least two at least two wireless device 300a, 300b.
Term sTTI is above for indicating short TTI, i.e., the TTI of short subframe.Short subframe can have compares 1ms in time
The shorter duration.Therefore, in step s 106 the TTI frequency band for wherein sending the license for wireless device 300a can be with
It is short TTI frequency band.STTI can be defined as the interval between than two continuous P DCCH transmission (such as every 1ms transmission primaries) more
It is short.In order to realize that delay is reduced, therefore network node 200 can be configured as raises in short time frame (for example, sTTI rank)
Degree evidence.
Now by open embodiment relevant to the further details to wireless device 300a granting resources.
Referring now to Figure 3, it illustrates according to other embodiments such as from network node 200 execute for wirelessly setting
The method of standby 300a granting resources.Assuming that step S102, S106 is being performed as reference Fig. 2 is disclosed, therefore omit
Repeated description to these steps.
According to embodiment, network node 200 is configured as providing the definition of sTTI frequency band to wireless device 300a, and because
This is configured as executing step S104:
S104: network node 200 sends message to wireless device 300a, wherein message definition sTTI frequency band.
The message sent in step S104 can be considered as permitting at a slow speed.
Step S104 can be executed after step s 102 but before step S106.
Message in step S104 can be used as the license to physical downlink control channel (PDCCH) to send, and
And provide the mark of sTTI frequency band.Alternatively, the message is sent using radio resource control (RRC) signaling.That is,
STTI frequency band can be configured by RRC or using PDCCH license, wherein the former constitutes semi-static distribution, and the latter can be pair
One subframe effectively dynamically distributes or to the effective Semi-persistent allocation of multiple subframes.
For example, the one or more region sPDSCH can be defined in sTTI frequency band.For using some of short TTI or institute
There are wireless device 300a, 300b, one or more sTTI frequency bands can be common.Multiple regions sPDSCH can be used for meeting
Use different subgroup wireless device 300a, 300b of sTTI.Other than the PDCCH region of distribution, each sTTI frequency band can
To occupy multiple resource blocks of entire subframe.Such as at a slow speed license in, sTTI frequency band can by PDCCH of every 1ms come
Definition.It can be directed to each sTTI, the one or more region sPDSCH is placed in sTTI frequency band, therefore sPDSCH becomes every
1ms is more than one.Therefore, the license sent in step s 106 can be used as quickly license and send on PDCCH, and provide
The mark of sTTI frequency band.Furthermore, it is possible to provide the license sent in step s 106 in the region sPDCCH of sTTI frequency band.Cause
This, PDCCH can define sTTI frequency band of every 1ms；And can to define every 1ms more frequently more than one by sPDCCH
SPDSCH (it is the subset of sTTI frequency band).Thus, it is possible to by the way that sPDSCH area maps are directed to the position of license
STTI data dispatch defines the symbol lengths search space for license.
Term " short PDSCH (sPDSCH) " indicates short physical down link sharing channel when using short subframe, and
Term " short PUSCH (sPUSCH) " indicates short physical uplink shared channel when using short subframe.Similarly, short
PDCCH (sPDCCH) is used to indicate that short physical downlink control channel when using short subframe, sDCI to make for indicating to work as
Short DCI (down link control information) and sCCE when with short subframe are used to indicate short CCE (control when using short subframe
Channel element processed).
License can be provided in short DCI (sDCI) message.In this respect, due to can be with every subframe repeatedly to wireless device
300a sends sTTI UL and DL scheduling, it is thus possible to need to limit the information content for including in sDCI message.As in step s 106
The index of transmission can be used to identify a configuration in predefined configuration set by wireless device 300a.Therefore, sDCI believes
Breath can be in the predefined sCCE pattern in the first OFDM symbol of downlink sTTI.Then, its in sTTI is remaining
Line link sTTI OFDM symbol (not including PDSCH reference symbol) can be used for sPDSCH.
Furthermore, it is possible to signal the instruction of the length (quantity of OFDM symbol) of sTTI in license.In addition, sTTI
Length can be given as DCI of every subframe, configured using RRC signaling or predefined.For example, institute as above
It states, RRC signaling can be used and send the message for defining sTTI frequency band.In other words, RRC signaling can be used to configure sTTI frequency
Band.
In order to make multiple wireless device 300a, 300b share available frequency resources, frequency partition is defined.It can be (as walked
Sent in rapid S104) it defines in license divide at a slow speed.Therefore, according to embodiment, the position identified is in sTTI frequency band
The region for resource initial position.The index can also identify placement of the region in sTTI frequency band.According to multiple
Aspect, (as sent in step s 106) to the quick license of each of wireless device 300a, 300b include as provided in table 1
Instruction.
| Label | Used region |
| 1/1 | Entire sTTI frequency band |
| 1/2 | The first half of sTTI frequency band |
| 2/2 | The latter half of sTTI frequency band |
| 1/4 | First a quarter part of sTTI frequency band |
| 2/4 | Second a quarter part of sTTI frequency band |
| 3/4 | The third a quarter part of sTTI frequency band |
| 4/4 | 4th a quarter part of sTTI frequency band |
Possible distribution in table 1:DL sTTI
STTI frequency band is divided into the quartering according to the non-limitative illustration example, allows four different wireless devices
300a, 300b access sTTI frequency band.However, frequency partition is not equally distributed according to some aspects.For example, can make to draw
The appearance part occurred partially than after before point is relatively broader, because the appearance part of front is more likely to be covered by DCI.
600 in Fig. 6 show it is according to the embodiment have permitted assignable sTTI.In the example of fig. 6, using 16
The sTTI frequency band of resource block (RB).Fig. 6 shows three examples to three wireless device 300a, 300b distribution resources.Upper
In portion, using the label in table 1, partially and in " 4/4 " part is dispatched in " 3/4 " be expressed as wirelessly setting for UE2 and UE3 respectively
It is standby, and scheduling is expressed as the wireless device of UE1 in " 1/2 " part.Therefore, according to embodiment, sTTI frequency band includes being directed to
At least two licenses of the resource for each wireless device 300a, 300b, and sTTI frequency band is divided into part.It can incite somebody to action
STTI frequency band is divided into the part with the quantity of wireless device 300a, 300b as many.Alternatively, sTTI frequency band is divided into more
Small part or more.As an example, some licenses can indicate UL resource, (some of wireless device 300a, 300b can
Only to receive UL license), then sTTI frequency band can be divided into the less part of quantity than wireless device 300a, 300b.
When wireless device 300a, 300b find its DCI at some position with DL license, it can be based on following situations
Determine PDSCH resource: firstly, all resources in division belong to this and wirelessly set if DCI is not disposed in assigned division
Standby 300a, 300b (such as the UE2 and UE3 in the top of Fig. 6).Therefore, according to embodiment, if being directed to wireless device
The license of given wireless device 300a in 300a, 300b is not disposed in from index to this and gives the part that wireless device 300a is identified
In, then belong to the given wireless device 300a by all resources in the part of index mark.Secondly, if DCI be placed in
In the division that wireless device 300a, 300b are assigned, then for the first symbol, belong to nothing for the resource on the right side of DCI in the division
Line equipment 300a, 300b (such as the UE1 in the top of Fig. 6).Therefore, according to embodiment, sTTI frequency band includes being directed to be used for
At least two licenses of the resource of each wireless device 300a, 300b, and the license finally occurred at least two license
Resource in sTTI frequency band at the earliest position in the resource for wireless device 300a, 300b.
The middle section of Fig. 6 show more resources for control scene.Particularly, according to embodiment, exist wherein
Two orthogonal frequency division multiplexing (OFDM) symbols of resource are assigned with, and the license includes mark, and the wherein mark
Indicate that the position of the resource in the sTTI frequency band is placed in which symbol in the two symbols.It can be introduced into as fixed in table 2
